With the continuous advancement of intelligent engineering in refining and chem-ical enterprises,information construction has become a key means to enhance the competitive-ness of enterprises,optimize the production process and improve management efficiency.How-ever,in the process of informatization construction for many years,due to the lack of unified planning and standards in the early exploration process,problems such as data dispersion,low quality,and poor security have arisen.Through the construction of operational data warehouse(ODS)system in refining and chemical enterprises,the problem of data sharing between multi-ple systems can be solved,data quality can be improved,data security can be guaranteed,and data analysis applications can be supported at enterprise level.On the basis of data warehouse theory and the background of ODS system construction,the framework and key technologies of data warehouse are studied.
